I thought of Iron Man when I read about Hyundai Mobis turning the windshield into a display, but not the armor or the billionaire part, because that is where the fantasy ends for most of us.

What came to mind was Tony Stark’s view inside the helmet, where information appears in front of his eyes while he still sees what is ahead.

Others may think of Pacific Rim, where Raleigh Becket and Mako Mori pilot the Jaeger Gipsy Danger from a cockpit filled with screens and warnings while facing Kaiju.

Hyundai Mobis is now bringing that cockpit-style display closer to real vehicles. The South Korean parts company has developed a holographic windshield display that can show navigation and key driving details on the front glass.

It uses a holographic optical element film inside the windshield and a projector that sends full-color images onto the glass. Hyundai Motor Group said Hyundai Mobis has formed an alliance with ZEISS, tesa and Saint-Gobain Sekurit, with mass production targeted by 2029.

Putting navigation guidance on the windshield can reduce the need to glance at a phone mount or center screen, but it also raises a bigger question on how much should appear on the glass while the vehicle is moving.

Filipino drivers already put plenty of things near the windshield, from RFID stickers and phone holders to small dashboard saints. And of course, the rosary.

Add a digital display to that space and the game changes. Navigation can help, but video is another matter.

The Philippines is a karaoke country, so someone, including a driver, will eventually ask if lyrics can appear during traffic. That sounds fun, yes, but while the car is moving, the answer should be no.

Hyundai Mobis said the technology can show key driving information on the windshield, while the passenger side can display separate content such as videos or games without being visible to the driver.

Safety should win here. Navigation and warnings can help, but even if a music video is not directly visible to the driver, “Hawak ko ang beat” on the windshield may still turn into a performance nobody wants to explain to the insurance company or the police.

If left unchecked, the front glass could also become another paid space for promos and pop-ups. That may be acceptable when the car is parked, but not while driving.

With speed and safety alerts already enough, the windshield does not need to become an advertising LED wall.

JARVIS on the windshield sounds cool, and Tony Stark would probably approve. Pacific Rim fans may also enjoy the flashing warnings before the Kaiju arrives.

On our roads, though, the threat is not a Kaiju rising from the sea. It is the small thing we fail to notice in time.

The windshield can become smarter, but it still has to stay a windshield. Its best future is to help us see the road better and bring everyone home safer.

But this is still the future we are talking about, and the next few years will show if this becomes a safety tool or another screen fighting for our attention.
